Centre revitalises its electrical infrastructure
This article will discuss the process behind developing and implementing a successful electrical infrastructure upgrade project that is applicable to a variety of healthcare infrastructure projects. A number of recent projects that have involved upgrading critical electrical infrastructure throughout Sunnybrook’s healthcare network will be reviewed, along with innovative features that have been incorporated.
Sunnybrook Health Sciences Centre is a full service, 1359-bed hospital located in Toronto, Ontario, the largest city in Canada, with a population of just over six million people. Sunnybrook is affiliated with the University of Toronto for academic health sciences, partnered with Veterans Affairs Canada and home to over 500 veterans. The hospital consists of three separate sites in the city of Toronto: the Bayview campus – the main three million square foot campus; the Holland campus – a 150,000 square foot site dedicated to orthopaedic and arthritic services; and St John’s Rehab campus – a 230,000 square foot site that provides specialised rehabilitation and support services. Sunnybrook’s real estate portfolio
consists of a multitude of buildings of varying ages, with the oldest dating back 70 plus years. The Bayview campus saw its first patients in 1946 and officially opened in 1948. The ancillary campuses are also of a similar age, with St John’s Rehab dating back to 1937 and the Holland campus dating back to 1955. With minimal opportunities for large scale redevelopment, Sunnybrook’s facilities group has been tasked with upgrading essential building services that have reached end of life conditions in buildings that will remain operational in the medium to long term future. While Sunnybrook’s oldest buildings
date back to the 1940s, most of the main electrical power system dates back to the 1970s and 1980s. Newer equipment has been installed in clinical areas that have been renovated over the years and in wings that have been added. Despite having an established preventive maintenance programme for electrical assets, issues with continued reliable operation have developed. Specific examples include: unexpected failures of medium voltage

cables and bus duct; difficulty with reclosing main switches after maintenance isolations; main power transformers where dissolved gas analysis indicates end of life conditions; and serviceability issues for emergency power systems that consisted of a combination of generators and control systems of varying ages and
from various manufacturers, with no single source of responsibility for the overall system. Recognising the importance of maintaining the reliable operation of healthcare services, Sunnybrook’s facilities and maintenance group sought professional engineering services to
